Wrong executionId when using Error Boundary Event

bkonrad — Thu, 10 Mar 2016 10:28:49 GMT

Hi,i have a problem getting the correct executionId in a Service Task which has a Error Boundary Event defined:[img]https://drive.google.com/file/d/0B4B-GQHdB3Xta0dELTJiSVpQRms/view?usp=sharing[/img]https://drive.google.com/file/d/0B4B-GQHdB3Xta0dELTJiSVpQRms/view?usp=sharingWhen the processinstance

Hi,

jUnit test would help (https://forums.activiti.org/content/sticky-how-write-unit-test), but I would say that boundary event is registered with the process instanceId.

But why does Activiti give me an exceutionId in the JavaDelegate of Task 1, which is NOT the processIntanceId?

Because a process instance is stored as an execution tree. The process instance does not visit the step, but a child execution does.
Use execution.getProcessInstanceId() from the execution in the JavaDelegate to get the process instance id.

Yes, this would solve my concrete problem here, but if I would like to reuse the same JavaDelegate in another process, where I have a parallel execution, i can not reuse it, because I need the specific executionId of my parallel execution

Why would you need in one instance the specific execution id and in the other the process instance id?
It's generally not a good idea to depend on the structure of the execution tree in logic, as it is completely dependent on the actual process definition structure.

You misunderstood me, what I mean is "in another process-definition" - not instance. We have many Processdefinitions, which use the same JavaDelegate Code.

So, having a Processdefinition with a Service Task in a parallel execution and having another Processdefinition with a Error-Boundary attached to a Service Task, both using the same JavaDelegate - what ID should I use? execution id vs. process instance id

I'm not misunderstanding you … I'll repeat my advice from previous comment: it's generally not a good practice to depend on the structure of the execution tree i.e. use the executionId.
